One of Jurgen Klopp's assistant knew Virgil van Dijk was the perfect signing after Liverpool's attack failed to get the better of him during a Premier League fixture.
It's five years since Van Dijk, 31, joined the Reds from Southampton in a £75million deal. The transfer raised eyebrows at the time due to the Netherlands international's huge price tag, but he's proved to be one of Liverpool's greatest ever signings.
Van Dijk has played more than 200 games and won seven trophies - including the Premier League title and Champions League - since the transfer. Liverpool coach Peter Krawietz has recalled the moment when they decided Van Dijk was worth investing in.
